ok so I just picked up a 97 legacy L wagon 2.2 auto. previous owner told me he was driving one day lost power and noticed the engine temp rising. when he got it off the trailer at his place he told me he noticed bubbles in the overflow tank and determined it was the head gasket.
after purchasing it last night I trailered it home drove it off the trailer and waited until this morning to check it out.
this morning I toped off the radiator, opened radiator the bleed screw, and put a little water in the overflow tank. immediately upon starting the engine I noticed bubbles in the overflow tank . I let it run to bring the engine to operating temp and open the t-stat. opened the bleed screw again and water bubbled out but never stopped bubbling. once I was satisfied that, under normal conditions, the engine would have been free of trapped air I reinstalled the bleed screw and let the engine run a while longer. while the bubbles never stopped i did notice the engine temp never went over the halfway mark on the temp gauge. while the engine was running I also noticed it has a slight misfire at idle. to investigate the misfire i removed and inspected all four spark plugs and noticed #3 was significantly darker with a rust like coating and wet threads.
now i am sure water is making its way into the #3 cylinder and i am going to remove the heads look for cracks and install new head gaskets.
My reason for this thread is to ask others who have had HG issues with the 2.2 for any tips they might have after their experience. P/Ns for gaskets, t-stats, timing belts, water pumps, etc..
also while i was researching i saw a post somewhere where someone insisted that people should only use Subaru HG's. Has anyone had issues with aftermarket parts? What other parts should i go straight to Subaru for?
What are good websites for Subaru parts?
Thanks in advance!
